(888) 312-8812 Login SignupThe Cummins Engine Heater Wiring Harness is the replacement you need when the engine heater stops warming the block before cold starts because of damaged wiring. Damaged insulation or corroded terminals can leave the heater dead on the coldest mornings, when it matters most. Routing the Cummins 3946907 in place of a damaged harness restores a safe power path to the heater. Warm engines start easier, use less battery, and wear less during startup.
